Pick N Pay Black Friday Con

I have available an email trail with Pick n Pay and find it disgusting that a corporate of this size and influence can behave like this. No wonder they face the negative business and financial issues they do. Very simple. Black Friday I order, online, a lawnmower at a discounted price with delivery shown for 6 December. On 3 December I am informed my 'deal' is cancelled but if I place a new order, at the normal price, I'll receive my lawnmower by the latest 5th, before the Black Friday delivery date ? No stock ? When querying how there can be stock to deliver at higher price but no stock to honor the deal concluded on Black Friday, both the customer care email and the actual individual who informed me of the cancellation ignore my emails even though I receive read receipts. Not getting the lawnmower is not going to kill me but the behavior of Pick n Pay leaves a very sour taste as they con individuals on Black Friday. Fortunately we have Checkers and can watch this once South African icon sink like it should. Regards
